PROFIBUS-DP: REMOTE I/O - Acromag

BusWorks® I/O Modules for Profibus-DPAcromag’s BusWorks 900PB series is a high-performance line of network-ready analog and discrete I/O modules. They feature universal input/output ranges and an intelligent microcontroller to provide extreme flexibility and powerful monitor-ing and control capabilities. Select from a variety of analog and discrete I/O models to meet your application requirements.

Each module provides a direct network interface for your I/O signals. Unlike “block I/O” devices that combine large, expensive processor blocks with snap-on I/O terminal blocks, 900PB modules handle the network interface and I/O processing in one, compact multi-channel module. This space-saving approach is very cost-effective for systems that need to add a small quantity of I/O channels at existing control sites or network to new remote sites.

To ensure high performance, modules feature an advanced microcontroller technology. On-board address switches and automatic baud rate detection (up to 12 Mbps) simplify installation. Four-way isolation prevents ground loops and increases noise immunity. Indicator LEDs and self-diagnostics help you quickly catch problems.

900PB SeriesProfiBus-DP I/O ModulesThe 900PB series is a high-performance line ofnetworked I/O modules. These units feature universal input/output ranges and an intelligentmicrocontroller to provide extreme flexibility andpowerful monitoring and control capabilities.Select from a variety of analog and discrete I/Omodels to meet your application requirements.

Each module provides a direct network interface for your I/O signals. Unlike “block I/O” devices that combine a large and expensive processor block with snap-on I/O terminal blocks, 900PB modules handle the network interface and I/O processing in a single, compact multi-channel module. This space-saving approach is very cost-effective for systems that need to add some I/O channels at an existing control site or network new, remote sites.

To ensure unsurpassed performance, these I/O modules employ advanced microcontroller tech-nology. Isolated input, output, power, and net-work circuits increase noise/transient immunity and prevent ground loops. Status LEDs provide diagnostic feedback.

Self-diagnostics and sophisticated watchdog timers simplify maintenance and troubleshooting. The watchdog timer invokes a failsafe condition if host communication is lost. For further security, a second watchdog monitors the microcontroller for failed operations or a “lock-up” condition and automatically resets the unit.

Ready to ship within 24-hours from stock. Backed by a 2-year warranty.

Easy to UseProfibus-DP networks offer several advantages.They are proven, fast (up to 12Mbps withoutfiber optic cable), deterministic, and ideal fortransmitting analog or discrete data. I/O devicesare also easy to install and maintain. More than1000 organizations worldwide, plus the ProfibusTrade Organization (PTO), help nurture a growinguser base, introduce new products, and providetechnical support for this network technology.

Network devices, including Acromag’s 900PB I/O modules, are easily installed and configuredusing network management software typicallyprovided by the supplier of the host or mastercontroller. The startup process is shown below.

Step 1: Set the slave addressUsing two rotary switches, as shown, set theslave address between 0 and 125 (00 to 7D Hex).The factory default setting is 126 (7EH) whichallows programming via the network. Once theaddress is set, the module may be physically connected to the network or master.

Step 2: Add the I/O module tothe network databaseEach I/O module, like all slave devices, is definedby a unique software file (*.gsd file). The GSDfile for each module is installed (or imported)into a network database for identification by thenetwork management software.

Acromag GSD files are supplied at no-chargewith each module. They are also available fordownload on the Acromag website or from thePTO at www.profibus.com.

Step 3: Configure the moduleUsing the network management software, youconfigure each device as desired (address,ranges, sensor break detection, failure modes,etc.). When finished, the software will downloadthe configuration to the master controller forcommunication.

Set switches to a valid slave address from 0 to 125 (00H to 7DH)

Step 1: Rotate the switches on top of each 900PB module to set the desired network address.

Step 2: The network management software (SyCon from Lantronix shown above) lists Profibus devices availablefor configuration after their GSD files are copied to the software’s directory using Windows Explorer.

Step 3: Above, a 12-channel analog input module(slave) is configured. A parameter data window showsthe user-selected voltage input ranges. The menu above lists input range options individually

selectable for each 4-channel group.

The following specifications are common to all900PB Series I/O modules.

n CommunicationInterface StandardIsolated, 3-wire RS-485 multi-drop, half-duplex, asynchronous.

Command/Response ProtocolStandard ProfiBus DP (Master/Slave) protocol perEuropean Norm EN50170.

Baud RateSupports rates of 9600, 19.2K, 44.45K, 93.75K, 187.5K,500K, 1.5M, and 12M bits per second, auto-detected.

Communication DistanceUp to 1200 meters without a repeater using Type Awire (<30pF/m).1200m @ 115Kbps or less1000m @ 187.5Kbps400m @ 500Kbps200m @ 1.5Mbps100m @ 12Mbps

AddressSet via two rotary hexadecimal switches or via the SetSlave Address command. Valid setting is 0-125.Address 126 (7EH) is factory default address.

Maximum Message SizeUp to 32 bytes recommended, extendable up to 244bytes of data/node/message, plus 11 bytes of over-head (data frame).

Network CapacityMulti-drop up to 31 modules, plus a host, without arepeater. Up to 125 modules plus a host if fourrepeaters are used (one for every 31 nodes).

n EnvironmentalIsolationI/O channel, power, and network circuits are isolatedfrom each other for common-mode voltages up to250VAC, or 354V DC off DC power ground, on a continuous basis (will withstand 1500VAC dielectricstrength test for one minute without breakdown).Complies with test requirements of ANSI/ISA-82.01-1988 for voltage rating specified.

n ElectromagneticCompatibility (EMC)Immunity per European Norm EN50082-1.Emissions per European Norm EN50081-1.

Electrostatic Discharge (ESD) ImmunityPer EN61000-4-2.

Radiated Field Immunity (RFI)Per EN61000-4-3 and ENV50204.

Electrical Fast Transient Immunity (EFT)Per EN61000-4-4.

Conducted RF Immunity (CRFI)Per EN61000-4-6.

Surge ImmunityPer EN61000-4-5.

Radiated Frequency EmissionsPer EN55022 Class B.

PROFIBUS RS485 NETWORK

A network segment may contain up to 32 nodes without the use of a signal repeater.Transmission distance is up to 1200 meters per segment without a repeater.A 120 ohm termination resistor must be placed at both ends of a network or network-segment.

The total number of nodes and total distance may be extended by using signal repeater(s).The maximum number of modules possible is further limited by the address range from 0 to 125.
